Despite having replied to a lot of these 'next AC game period', I still get tired of them less easily than AC:B's freakin' gameplay, that's for sure... -_- *sigh*
Anyway, Napoleonic Wars... the whole damned saga from 1789-1815 (what?! ACII lasted almost as long as that, and the fucker's only just quit!). The possiblities are almost innumerable (and that's just in GB/France/Spain), and we can return to the name-dropping that made the first two games soooooooooooooo much more engaging (for me at least)...
